Application filed April 14, 1927. Serial No. 183,708. i

This invention relates to Vmixing machines and is particularly directedto -a concrete mixer. l

Objects of'this invention Vare tov provideV i a novel form ofconcretemixer in which a mixing vessel is provided and associated with acharging bucket, and in which means are provided for elevating thecharging bucket so thatit is'raised bodily and tilted member beingchannel-shaped for the re-l ception of the flexible elements.

Further objects are to lprovide a novel form of concrete mixer whichiS-of extremely simple and eminently practical construction, which maybe cheaply made, and which supports a bucket in a manner to permit itsready shaking to dislodge the material therefrom.

An embodiment of the invention is shown in the accompanying drawings, inwhich:

Figure l is a. sectional view 'on the line 1 1 of Figure 3, showing infull lines the bucket in charge receiving position, and in dotted linesin discharging position.

Figure 2 is a fragmentary view ofy the guiding means showing the bucketpartly elevated.

Figure 3 is a plan view of the structure shown in -Figure 1.

Referring to the drawings, it will be seen that the concrete mixerchosen for illustration consists of a mixing vessel 1 carried in f theusual manner by a frame 2. This frame is provided with plates 3 onopposite sides and the plates 3 carry tracks l formedof angle iron withthe flanges 4 located on the outer sides, as may be seen from Figures 1and 3. Theframe is also provided with guiding pulleys 5 for theelevating cables 6.

The charging bucket 7 is carried by a pair of channel iron bars-lwhichlextend diago' nally inwardly when .the bucket is'iinits. i

loWcrInost position, asshown in full linesin Figure These channel ironbars carry channel-shaped rolling means 9 which are adapted to travelupon thetrack lyas' shown in Figures 1 and2. yThe members 9, as stated,are adaptedV to receive 'Within themselves flexible z suspension meansVAwhich may take the form of a' chainlO and which, e '1s duplicated onopposite sides jofgthe-.ma-A

chine. These suspension elements or chains are secured at their upperends to the frame through the medium of the track and at their lowerends to the rolling channel shapedmembers 9.

lf desired the tracks lmay have inwardly turned upper portions .11 so asto permit a quick inward motion of the' bucket at" the completion of itsupward stroke, so asto start the material downwardly and inward ly fromthe bucket.

From the description and illustration, itu

is apparent that when the outer end of the bucket is elevated, themembers 9 will roll upon the ltrack 4 and will wind up the chains 10.This is also readilyapparent from' the fact that the bucket tends torock inwardly and constantly forces the Arolling members 9 into contactwith the track 4. .As

tinuously shifting center. This permits the necessary motion ortranslation for elevating the bucket bodily and also imparts to thebucket a rocking motion to cause it to discharge into the mixing vesselwhen it is in the dotted line position Shown in Figure 1.

It is to be noted particularly that the Suspension members permit theready` lateral shaking of the bucket with the utmost easev as it is notrigidly connected to the frame` work, but is suspended by flexiblemembers. This results in the ready loosening of anyV adhering materialand its discharge into the mixing vessel.

It is to be noted, also, that scarcely any machine work `is required inthe production j of this type and that the partsmay be readily formedfrom standard stock with the utmost cheapness. Further it will be seenthat the device is eminently practical and is of rugged and substantialformation.` Although the invention hasbeen described, in considerabledetail, such description is in- 85 f the Vbucket is elevated it rocksabout a'l con- 7' V` tended as illustrative rather V.than "limiting asthe invention maybe variouslyT4 embodied and as the scope of suchinvention -is-to-Jbe ing vessel, a frame supporting said --vesse1 acharging bucket, elevating means for raislng the outery end ofsardabueket, andfguid- 1o lng means adjacent the inner end of saidbucket, Saicl.,gi1idin'gr means consisting of a pair 'of guiding.felementslocated ,on foppo site.sidesofsai'drbucket andeach pairI con'-sistingfof saxtrack Aand a A`curved .member ffor rolling upon lsaidltrack,.ith-e `,lower fends fof saidftracks bei-ng locate'd .inwardly`rbeneath said .mixing vessel, whereby Aas said bucket isf,.raised,`thecenter about'Which pivots movesfupW-ardly-and outwardly with refer-Y'encerfto said mixing vessel.
